Device, in particular a device for capillary chromatography. Also method for controlling the cooling of a component (8) of such a device. The device is provided with a cover (25, 25') which is arranged a short distance from a component (8) of the device and forms together with the device a space (26, 26') which space adjoins the component, wherein the geometry of the space, for instance the distance between the cover and the component, is chosen such that the space, the cover and the device together have the thermal properties required for a determined desired cooling characteristic of the component. Preferably the cover makes thermal contact, for instance by means of resilient contacts (28), with a heat sink, for instance a metal plate (27). The space can be filled with a fluid, for instance a gas, for instance air. The desired or required thermal properties can be chosen or variably regulated by selecting or adjusting the geometry of the space and/or selecting the type of fluid and/or selecting or regulating the mass density of the fluid. The cooling characteristic of the component can thus be controlled very precisely.
